The story highlights the significance of standards like ASTM D618-21 in ensuring the quality and performance of plastic products. By following these standards, manufacturers can minimize errors, ensure consistency, and deliver high-quality products to their customers.
Conditioning and testing are essential steps in the evaluation of plastics. Conditioning refers to the process of exposing plastics to specific environmental conditions, such as temperature, humidity, and pressure, to stabilize their properties. Testing, on the other hand, involves measuring the physical, mechanical, and chemical properties of plastics to assess their performance.
Without conditioning, residual stresses from molding or environmental fluctuations can skew results. The standard provides two primary conditioning procedures:
